7 Quick Substitutes for Custard Powder
Here are our top seven picks for custard powder substitutes.
1 – Cornstarch and Vanilla Extract
Cornstarch and vanilla extract work together when we need a custard powder substitute. We mix 1 tablespoon of cornstarch with a splash of vanilla extract for every tablespoon of custard powder.

The texture stays smooth, and the flavor feels the same. Cornstarch is easy to find and keeps things simple.
Vanilla extract balances the mix without overpowering other ingredients. It’s an easy fix with ingredients we usually have around. Plus, the ratio makes adjusting for recipes a breeze.
